3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1 slush skin of instrument panel
surface softening decorative piece that the polyvinyl chloride powder is
attached to the surface of the preheated mold by rotating the uniform station,
and the interior of the automobile produced by the molding process of "loading"
the powdered material by plasticizing and cooling without pressure is decorative;
the shape of the mold is consistent
3.2 positive skin
decorative surface after softening parts are made
3.3 negative skin
surface that is relative to the positive skin
Gloss meter. shall meet the requirements of GB/T 9754-2007.
5.2.2 Test steps
Take 3 samples according to GB/T 9754-2007. Determine the gloss of the
positive skin of the sample by a single angle measurement (60°). The test
results are expressed as the arithmetic mean of the three samples.
5.3 Color
5.3.1 Instruments
Color difference meter (also called spectrophotometer). can choose 45°/0° or
d/8° measurement method, generally agreed by both parties.
5.3.2 Test steps
At least perform 5 individual measurements, the measurement position is
distributed over the entire surface. The results are generally agreed by both
parties.
5.4 Thickness
5.4.1 Instruments
Thickness gauge. accuracy is not less than 0. 01 mm, thickness gauge load is
393 g, presser foot diameter is 10 mm. The thickness gauge load and the
presser foot diameter can be agreed by the supplier and the purchaser.
5.4.2 Test steps
Take 3 pieces of 50 mm × 50 mm samples. Place the patterned side of the
sample face down on the gauge. Select two points, each point is not less than
5 mm from the edge of the sample, and the distance between the two points is
not less than 10 mm. Determine the thickness of the sample, to the nearest of
0.0.1 mm. The test results are expressed as the arithmetic mean of 6 test points.
5.5 Areal density
5.5.1 Instruments
Analytical balance. to the nearest of 0.1 mg.
5.5.2 Test steps
Take 3 flat pieces of 100mm × 100mm samples. Weigh separately on the
analytical balance, to the nearest of 0.1 mg. And convert the measurement
results to grams per square meter. The test results are expressed as the
arithmetic mean of 3 samples, in integer.
Reference material. DOP (dioctyl phthalate), requiring analytically pure DOP.
5.9.2 Test steps
The sample shall be dried in the dryer for at least 24 h before the test.
The test is carried out in accordance with the provisions of ISO 6452.2000. Take
2 samples with a diameter of 80 mm and place them in the glass of the atomizer
(the front side of the skin is placed up). Press the sample with a metal ring. Take
a glass at the same time and put in (10.0±0.2) g of DOP. Place the glass in the
oil bath. Put the sealing ring, the weighed aluminum pin (G0), the round glass
plate, the filter paper and the cooling plate on the edge of the glass cup. The oil
temperature is controlled at (100±0.5)°C, the temperature of the cooling plate
is controlled at (21±1)°C, and is maintained (16±0.2) h. After removing the
cooling plate, filter paper, and glass plate in turn, carefully remove the aluminum
foil, and place the fogged side of the aluminum foil upward, and store it in the
dryer for 3.5h ~ 4h. Weigh the aluminum foil (G1) that has been fogged and
store in the dryer. The difference between G1 and G0 is the test result. The
sample results are expressed as the arithmetic mean of two samples.
It shall confirm whether the condensation value of DOP is between (4.9±0.25)
mg (only when the oil temperature is 100°C). If the condensation value of DOP
is not in this range, the test shall be invalid, the cause shall be analyzed, and
the test shall be repeated.
In special cases, the test temperature and storage time can be negotiated
between the supplier and the purchaser.
5.10 Resistance to Xenon aging
5.10.1 Equipment
Xenon lamp aging chamber. in accordance with GB/T 16422.1-2006.
The filter system uses a combination of a glazed glass inner filter and a
uranium-calcium glass outer filter.
Reference material. No. 6 blue wool, in accordance with ISO 105-B06.1998.
5.10.2 Test steps
According to the provisions of GB/T 16422.2-1999, take 3 pieces of 140mm ×
70mm samples and 1 blue wool as reference material of the same size. Place
the sample and reference material in a Xenon lamp aging chamber. The sample
is facing the light source. Carry out 5 cycles of exposure tests under the
conditions that the black mark temperature is (100±3)°C, the test chamber
temperature (65±3)°C, the relative humidity is (20±10)%, and the spectral
intensity of 420 nm is 1.2 W/m2, without spray. The determination of the end
Level 1. feel no smell;
Level 2. feel the smell, but not irritating to people;
Level 3. obviously feel the smell, but not irritating to people;
Level 4. obviously feel the smell, irritating to people;
Level 5. the smell is very strong to people;
Level 6. the smell is very strong and unbearable.
